Londoner moving to New York for work. Looking for a room in a 3 or 4 bed with roommates who are up for a good time on weekends but don't bring the party home on weeknights.

I work for a tech company in London and asked to transfer to New York and to my surprise they said yes!
I should be arriving at the start of January and am looking for a room, ideally in Williamsburg, but am open to other suggestions too.

I'd like to find easy going flatmates who won't mind me having people to visit every so often. People who don't bring the party home on weekdays but ideally like to have fun on weekends. During the week when I'm not working I exercise, but mainly love chilling out at home, having dinner parties, watching TV and relaxing. On weekends I hope to be exploring as much of New York as possible, stuffing myself with as much food as possible, and also expect to be travelling round the US a fair amount for work and play.
